Micro-porous ceramic filter brick, plate and pipe are composed of aggregate grains,binder and pore-forming agent,Interlinking arched open pores are formed on their surfaces and the interiors thereof by baking at high temperature.Various physical-chemical reactions are caused by on the surfaces and in the interiors of these pores by fluid passing through therein to realize purification and filtering functions.The Micro-porous ceramic filter brick,plate and pipe are especially applicable to operations including liquid filtration and gas filter fluidization etc.such as the filtration process during the separation of ash water in boiler dust removal through wet method and the preparation of tapwater ,industrial water and pure water.In addition,they can be used as catalyst carriers and infrared radiation plates
